The Development of Substation Automation System for Electrical Device’s Operation and Management

In substation automation system,with the aid of computer,the economical operation of parallel transformer system is implemented;normal over load operation and incident over load operation management according to the allowable over load conditions are achieved;by calculation the hottest point's temperature of operating transformer,and according to the 6℃ norm,the transformer's life loss management is implemented;and according to the features of distribution line,the measurement of load point's voltages is realized.All these raise substation's operation and management level.
